Pigtail and Plug-On Neutral
Pigtail Plug-On Neutral
Siemens Tandem AFCI Breakers are the perfect solution to wiring made easier. The design allows for more circuits in a smaller loadcenter. Installed indicator flags disappear when the load wires are inserted correctly.
Siemens CAFCI Plug-On breakers now have a single load lug(s) only. Wiring made easier with the neutral lug removed. These breakers can be installed in the same manner as the thermal magnetic breakers. This allows the installer to land ground and neutral conductors in the load center before installing the breaker and load conductor.
Tandem AFCI breakers without the rejection feature can be installed in any panel that lists that breaker type or where a substitution letter exists for that breaker type. The schematic, located on the wiring diagram, will indicate the positions where these breakers can be placed by showing two circuits per space. The total circuits listed for panel should not be exceeded.
